Chemistry - Thermodynamics - I Question with Solution | TestHub

Hyperconjugation involves overlapping of (filled) hybridised orbital (sp³–s) with (empty) unhybridised p orbital.

More the number of hyperconjugating structures more will be the stability of the molecule. Hyperconjugation is used to compare heat of combustion and heat of hydrogenation as number of carbon atom increases heat of combustion increases and as the number of π bond increases heat of hydrogenation increases. (also as stability increases value of heat of hydrogenation decreases)
